Yahoo! Mail

This page is currently a placeholder for describing hints and tips for
using JavaMail with Yahoo! Mail. Basic Yahoo! Mail usage information
can be found in the
JavaMail FAQ.

See also the
Wikipedia page on Yahoo! Mail
for information about accessing the Yahoo! Mail IMAP server. I’ve just
added a feature to JavaMail to enable Yahoo! Mail IMAP server support -
set the property “mail.imap.yahoo.guid” to “1”. As of 3/19/2015, this
no longer seems to be necessary.

On 3/12/2015 a user reported
that using the JavaMail equivalent of UID FETCH X:Y (UID) where X is
greater than any existing UID in the folder never returns.

As of 8/19/2015, Yahoo Mail doesn’t handle some IMAP SEARCH terms
correctly. For example, the NOT term seems to be completely ignored.
